The river that flows through Egypt and Sudan is the Nile River. Known as one of the longest rivers in the world, the Nile is approximately 6,650 kilometers (4,130 miles) long and has been a lifeline for civilizations in the region for millennia. It flows through several countries before emptying into the Mediterranean Sea, forming the Nile Delta. The river's waters are essential for agriculture, drinking, and transportation, underpinning the economic and cultural life of the societies that rely on it.
